taylor f(x)=ln(x)

taylor

f (x) = ln (x)

(x - 1) - \frac{1}{2} (x - 1)^{2} + \frac{1}{3} (x - 1)^{3} - \frac{1}{4} (x - 1)^{4} + \frac{1}{5} (x - 1)^{5} + \dots

Solution steps

Apply the Taylor Formula

= 0 + \frac{\frac{d}{d x} ( ln ( x ) ) ( 1 )}{1 !} (x - 1) + \frac{\frac{d ^{2}}{d x ^{2}} ( ln ( x ) ) ( 1 )}{2 !} (x - 1)^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( ln ( x ) ) ( 1 )}{3 !} (x - 1)^{3} + \dots

Evaluate Derivatives

= 0 + \frac{1}{1 !} (x - 1) + \frac{- 1}{2 !} (x - 1)^{2} + \frac{2}{3 !} (x - 1)^{3} + \frac{- 6}{4 !} (x - 1)^{4} + \frac{24}{5 !} (x - 1)^{5} + \dots

Refine

= (x - 1) - \frac{1}{2} (x - 1)^{2} + \frac{1}{3} (x - 1)^{3} - \frac{1}{4} (x - 1)^{4} + \frac{1}{5} (x - 1)^{5} + \dots

x \to 0 lim (x ln (3 x))

k \to 0 lim (\frac{( 2 z + 3 k ) ^{3} - 4 k ^{2} z}{2 z ( 2 z - k ) ^{2}})

\int_{2}^{\infty} \frac{2}{x ^{2} - x} d x

\frac{d}{d x} (ln (x ln (x)))

\frac{d y}{d x} = 5^{x} ln (5) + \frac{2}{x ^{2} + 1}
